This invention .relatesto a seat-construe tion, more particularlyto the mounting for the seat, whereby it maybe moved to different positions, for example, forwardly or back- Wardly, toward and. from the foot controls of a vehicle, as well' as-its steering device:

One object of the invention is to provide a seat mounting which isrelatively simple and Capable ofpositive operation to move the seat 7 anydesired distance Within the limits of its movement in eitherdirection.

Another object of the invention is to'provide aseat mounting capableof ready adj 11stment when ocoupled withoutundueexertion ormanualeffort;

and engaging the lower face of the plate 3 to prevent upward tilting of the seat, the de vice 3 being removably held on the bolt 3 by a nut 3. As the slots 3 are parallel, the walls thereof will. guide the bolts 3 during adjustment of the seat.

The adjustment mechanism 4; consists of an operating means 5 and a set or sets of cooperable adjusting devices 5 actuated and controlled by the operating means 5. The operating means preferably comprises the following instrumentalities:

6 indicates a casting suitably secured, as by devices 6, to the under surface of the base 1", that is, the lower side of the front section of the frame, and movable therewith, and preferably disposed substantially midway between the ends of the section. The casting 6 has a base portion 6 and depending brackets 7, 8, provided with hollow bosses 9 forming bearings for a shaft 10. 11 is a separate casting secured by cap screws 12 or otherwise to the inner end of the casting 6, the walls of these castings being fashioned or shaped to form between them a box or casinglfor a worm 13 and a worm gear 1 2 in mesh therewith, the former being secured to the shaft and the latter being secured to a shaft 15. The end wall of the casting 11 has a thickened portion bored out, as shown at 16, to form a bearing for the inner end of the shaft 10, the worm 13 being mounted on the shaft 10 between the bearing 16 and adjacent bearing 9; whereas the abutting edges of the castings 6 and 11 have related semi-circular portions which form bearings for the opposite ends of the shaft 15. The shaft 10 extends outwardly through an opening formed in the section 3, as shown in Fig. 4, and carries on its free end a crank or handle 17 by means of which it may be readily rotated in either direction. The shaft 10 is preferably sectional, the adjoining ends of the sections being connected preferably by male and female elements. As shown, the inner endof the outer section engages the inner bearing 9 to prevent inward movement of the shaft and a collar 18 fixed to the outer shaft section engages the inner side of the outer bearing 9 to prevent outward move ment of the shaft.

Where the operatin means is mounted centrally of the seat 1, T prefer to provide at either side thereof a set of co-operable devices 5 arranged to be actuated simultaneously by the shaft when rotated in either direction, but in some other arrangement one set may be sufficient. In the illustrated arrangen'ient both side portions of the seat 1 are moved and therefore any tendency to wedge either side or endof the seat is avoided. As the sets of adjusting devices 5 are similar in construction, I will refer to but one thereof, as follows: 19, 20, indicate a pair of superposed plates having face to face engagement and slidable one relative to the other. In the preferred arrangement, the upper plate slidably bears upon the lower plate 19 and therefore the latter sustains a portion of the weight of the seat, but this is not essential, as the seat may be slidably supported at its front portion on the support 3 rather than by means of the plates 19, 20. The lower plate 19 is provided with a flange 19 and a guide and stiffening wall 19 at its outer end. The flange 19 is secured to the front supporting section 3" by bolts 21. The upper plate 20 is flanged upwardly at its front and rear edges and downwardly along its outer sine edge as shown at 20'. v The front and rear flanges are preferably secured to the front section of the seat base 1 as shown in Fig. 6 whereas the side flange 20 cooperates with the wall 19 to guide the front portion of the seat. Each plate 19, 20, is provided with a guide wall or walls disposed at an angle to the guide wall or walls on the other plate and disposed in a plane which intersects the latter. The guide wall or walls on each plate is provided by forming therein an elongated slot 22, preferably straight from end to end, at least one (either one) of the slots being disposed at a suitable angle (preferably to an imagt nary line extending at right angles to the direction in which the seat moves when adjusted. As it is desired to adjust the seat toward or from the foot controls A, this imaginary line extends transversely of the vehicle 13. By preference, both slots 22 are inclined at the same angle, but in reverse relation and one intersects the other so that a'portion of one always registers with a portion of the other in any and all positions of the seat. 23 indicates a device, such as a bolt or shaft extend ing through the slots 22, 22, and rotatably supported at its opposite ends in the bifurcations of a thrust member 24, the device being headed at one end and provided at its opposite end with threads to take a nut 25, whereby the deviceis supported in the bifurcations, and held against endwise movement. .26 indicates slides, such as rollers loosely mounted on the device 23 having their inner ends'in face to face relation and engaging respectively with and adapted to slide or roll on the side walls of the adjacent slots 22, the

body portions of the rollers having a diameter slightly less than the width of the slots. As showin'the rollers are flanged on their opposite outer ends and these flanges slidably engage the exposed faces of the plates 19, 26, and serve to space thebifurcations of the thri lst member 2 1- from the plates 19, 20, to avoid friction. As shown, the body portion of each roller 26 has a width substantially equal to the thickness of the adjacent plate and the length of the device 23 such to maintain the body the slots 22 so that'these portions may engage the sides thereof throughout their movemeht is D portions of the rollers in r in the site in eitheridirection and the flanges of -the lower slide-26 engage the plate 19 to prevent upward'tilting'of the 'front portion;

of the seat.

The inner end of thelthrust member is formedwitha longitudinally-extending'threaded opening 27 in and through I which'is threaded a feed screw 28. The-1m nerzend of the feed screw is connected, prefer'ablyby a universal joint 29fto the adjacent end voftheshaft 15, whereby rotation ofthe latter will rotate the feedscrew 28,which' in i turn will move the thrust member 24 endwise outwardly or inwardly ac'cordin'g'to the di-, ree'tion of rotation of the shaft; 1
